Landslide and flood damage in Rodeio, Santa Catarina, Brazil, January 2023.
The Civil Defense of the State maintains the alert for this Friday, 20, due to the indication of more rain for Santa Catarina.
So far the state government said 26 municipalities have reported losses due to the storms of recent days and the cities of Rio Negrinho and Ascurra have declared a state of emergency.

A collapsed hoop house at the U.S. Geological Survey on Switzer Mesa collapsed under the weight of snow following a series of winter storms that dropped more than 3 feet of snow on Flagstaff. The three hoop houses are part of an experiment to test drought tolerance of native plants from the Colorado Plateau.
Angelina Grubb is with the Arizona Snowbowl. She said skiers and snowboarders will have plenty of fresh powder this weekend.
"It's been great to see that much snowfall so early in the season, and so we're really happy about it," Grubb said.
Heavy rainfall this week across the Balkans has caused rivers to rise dangerously in Serbia, Bosnia and Montenegro, flooding some areas and threatening flood defenses elsewhere.
Floods were also reported in Kosovo and Albania, where high waters soaked agricultural land, blocked roads and caused temporary power outages.
In northern Albania, the local power company had to open sluices and release water from bulging reservoirs, flooding nearby areas for a third time in as many months.
In northern Kosovo, authorities said parts of the town of Mitrovica have been flooded, forcing people to evacuate their homes.
This is a disconnection event: A piece of Comet ZTF's tail has been pinched off and is being carried away by the solar wind.
Blame space weather. CMEs hitting comets can cause magnetic reconnection in comet tails, sometimes ripping them off entirely. NASA's STEREO-A spacecraft watched this happen to Comet Encke in April 2007: movie.
This month, multiple CMEs have swept past Comet ZTF as a result of surging solar activity. One of them is responsible for the disconnection event.
Soon, we'll get a better look. Comet ZTF is approaching Earth for a close encounter (0.28 AU) on Feb. 1st. Between now and then, the comet's brightness will cross the threshold of naked-eye visibility, possibly peaking at magnitude +5. CME effects will be increasingly visible as the comet approaches. Stay tuned!

Bearizona keepers report that the park has received more than 28 inches of snow at the wildlife park!
The Flagstaff Airport measured 14.8 inches on Sunday, smashing the previous record of 8.9 inches that held for 45 years. As snow continued to fall, accumulation eventually reached 30 inches at the airport by Tuesday morning.
The last time Flagstaff saw a storm of this magnitude was in late January 2021 when officials measured a 33.2-inch snowfall.
The areas impacted by the storm were expansive, said meteorologist Benjamin Peterson, including most areas at elevation above 5,500 feet, stretching from the northern rim of the Grand Canyon east to the White Mountains.

In this June 15, 2014, file photo released by the U.S. Geological Survey, a polar bear dries off after taking a swim in the Chukchi Sea in Alaska. A polar bear has attacked and killed two people in a remote village in western Alaska, according to state troopers who said they received the report of the attack on Tuesday, Jan 17, 2023, in Wales, on the western tip of the Seward Peninsula.
Alaska State Troopers said they received the report of the attack at 2:30 p.m. Tuesday in Wales, on the western tip of the Seward Peninsula, KTUU reported.
"Initial reports indicate that a polar bear had entered the community and had chased multiple residents," troopers wrote.
"The bear fatally attacked an adult female and juvenile male."
